This article is about all the easy-to-understand code examples of the Nashorn JavaScript engine. The Nashorn JavaScript engine is part of Java SE 8 and competes with other standalone engines like Google V8 (which is the engine for Google Chrome and Node.js). Nashorn extends Java's ability to run dynamic JavaScript scripts on the JVM. In the next 15 minutes or so, you'll learn how to dynamically run JavaScript on the JVM. Demonstrate recent Nashorn language features with some short code examples. Learn how Java and JavaScript call each other. Finally, it includes how to integrate dynamic scripts into your daily Java business.

2. php automatically loads objects
##Introduction: Many developers create a PHP source file for each class definition when writing object-oriented applications. A big annoyance is having to write a long list of include files (one file per class) at the beginning of each script. In PHP 5, this is no longer necessary. You can define an __autoload() function that is automatically called when trying to use a class that has not yet been defined. By calling this function, the scripting engine has a last chance to load the required classes before PHP fails with an error.

7. php automatic loading class__autoload() function usage method
Introduction: When developing object-oriented applications in PHP, it is often necessary to call various class libraries, so it is inevitable to use require or include to reference the class library when using these libraries. Now the __autoload() function can give us a lot of convenience. In PHP 5, you can define an __autoload() function that will be automatically called when trying to use a class that has not yet been defined. By calling this function, the script engine will fail in PHP 8.

Monitoring and managing Xcache status # #Introduction: Xcache is a commonly used Opcode cache. In many cases, in order to make script execution more efficient, we can use this cache. It allows the script engine to not have to compile and execute every time, but can do it once After compilation, cache the Opcode and execute it directly. The efficiency will increase by about 30%-40%. When the PHP file is changed, Xcache [Related Q&A recommendations]: javascript - What are the differences in the DOM tree parsing and script execution order of each script engine?

Java code will have performance differences when running on different platforms. 1) The implementation and optimization strategies of JVM are different, such as OracleJDK and OpenJDK. 2) The characteristics of the operating system, such as memory management and thread scheduling, will also affect performance. 3) Performance can be improved by selecting the appropriate JVM, adjusting JVM parameters and code optimization.

Reasons for writing platform-specific code in Java include access to specific operating system features, interacting with specific hardware, and optimizing performance. 1) Use JNA or JNI to access the Windows registry; 2) Interact with Linux-specific hardware drivers through JNI; 3) Use Metal to optimize gaming performance on macOS through JNI. Nevertheless, writing platform-specific code can affect the portability of the code, increase complexity, and potentially pose performance overhead and security risks.

Java will further enhance platform independence through cloud-native applications, multi-platform deployment and cross-language interoperability. 1) Cloud native applications will use GraalVM and Quarkus to increase startup speed. 2) Java will be extended to embedded devices, mobile devices and quantum computers. 3) Through GraalVM, Java will seamlessly integrate with languages such as Python and JavaScript to enhance cross-language interoperability.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
